Description

***消息更新指示的方法、装置及*** 技术领域
本发明涉及通信领域，具体而言，涉及一种***消息更新指示的方法、装置及***。
背景技术
机器间(M2M，Machine to Machine)通信是第五代移动通信技术(5G，5th Generation)研究的一个重要课题，也是未来无线通信的一个重要应用领域。在M2M课题里，针对低成本低吞吐量类型终端的特性，第三代合作伙伴计划(3GPP)提出了窄带物联网(NB-IoT，NarowBand Internet of Things)***的研究子课题，目标是在200千赫兹(KHz)的频带内构建一个和长期演进(LTE)相似的***，为低成本终端提供低吞吐量的无线通讯服务。
***消息(SI，system information)为小区的公共消息，用于指示小区的***参数，用户设备(UE)驻留在小区中必须保持对最新的***消息的一致；***消息通常承载在小区的广播信道上发送。在LTE和NB-IoT***中，***消息分为主信息块(MIB，master information block)和***信息块(SIB，system information block)两个类别，SIB又细分为SIB1、SIB2和SIB3等编号不同的***消息块。除SIB1之外的***消息块组成一个或一个以上SI。SIB1中携带有组成的SI的调度信息，调度信息用于指示每个SI包含的***消息块的编号、发送周期以及UE接收这些SI的时间窗口。
图1为根据本发明相关技术中的传统LTE(Legacy LTE)的***消息的更新示意图，如图1所示，***消息按照广播公共控制信道的修改周期(BCCH modification period，本文简称为修改周期)的机制进行更新，在***消息需要发生变更时，基站首先在第一个修改周期内通过寻呼消息(paging message)中携带UE***消息更新指示；然后，在第二个修改周期(第二个修改周期为第一个修改周期的在后修改周期)开始发送更新后的***消息，接收到携带更新指示的寻呼消息的UE在第二个修改周期接收更新的***消息。除了需要快速变化的***消息，其它的***消息在第二个修改周期内保持不变。
UE在第一修改周期内监听寻呼消息，如果在一个BCCH周期内都没有监听到任何寻呼消息，则UE在下一个修改周期开始时，主动读取***信息块SIB1,中携带的***消息值标签value tag，并与UE本地保存的有效***消息值标签进行比较来检查是否有***消息更新。这是为了防止因为UE接收寻呼消息的解码错误导致错过***消息更新的一种方式。
在最新的3GPP讨论中，达成如下的一致，对配置扩展非连续接收(eDRX)的UE，***为之配置如下机制：首先，此类UE在其配置的eDRX周期醒来后，在所谓PTW(paging transmission window)的寻呼发送窗中监听其寻呼消息。图2为根据本发明相关技术中的eDRX中UE的PTW示意图，所述的PTW的如图2所示。其PTW在其开始H-SFN中的起始SFN，按照如下规则确定：UE的PTW起点均匀的分布在一个paging hyper-SFN中，其具体起点与 UE的标识有关。
其PTW的长度为可配置的时间间隔。UE在其PTW窗内监听所有的PO(paging occasion)，其PO按照传统LTE的方式进行确定，即，根据其short短paging周期(short paging cycle)和UE标识，确定在一个paging cycle中寻呼无线帧PF(paging frame)和PO。
同样的，在eDRX的讨论中，对***消息的更新机制有如下的方法：***在m_eDRX(max eDRX cycle)内发送***消息更新的paging消息，指示UE在下一个m_eDRX周期开始时接收***消息的更新。UE在接收到该***消息更新指示后，在下一个m_eDRX周期开始接受更新的***消息。
在物联网的窄带***中，一个小区的带宽资源非常有限，相对传统LTE的带宽，窄带***的带宽只有其1/100或更少，在如此有限的带宽资源上如何更有效的实现***消息更新的寻呼消息发送，对提高窄带***小区资源利用效率的重要因素，而且，进一步的考虑到，为提高窄带小区的覆盖范围，每一次的寻呼消息发送需要重复几十到上百次，也就是说，传统LTE中一个PO只需要一个无线子帧，而在窄带***中，一个PO需要占用几十上百个无线子帧的相应资源，这取决于***消息更新指示的具体发送方式。
针对相关技术中在进行***消息更新指示时窄带***资源利用效率低的问题，目前尚未发现有效的解决方案。

在本实施例中提供了一种***消息更新指示的方法，应用在网络侧，图3是根据本发明实施例的一种***消息更新指示的方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，基站将***消息的***消息更新时间间隔T-SI-Update划分为多个***消息更新指示寻呼周期T-SI-Paging时间间隔；

通过上述步骤，采用基站将***消息的***消息更新时间间隔T-SI-Update划分为多个***消息更新指示寻呼周期T-SI-Paging时间间隔,然后基站在一个或多个T-SI-Paging时间间隔中发送携带***消息更新指示的寻呼消息，进而***消息更新指示的接收方可以在对应的时间间隔内接收到该寻呼消息，而不需要一直检测接收等待***消息更新指示，解决了相关技术中在进行***消息更新指示时窄带***资源利用效率低的问题，在可以接收寻呼消息的前提下，提高窄带***资源利用效率，进而达到了节约***开销的技术的效果。
通过本实施例，基站在没有***消息更新时，在上述的T-SI-Paging中指示UE没有***消息更新，使得UE不需要因为怀疑没有正确的解调寻呼消息，而额外的读取MIB或SIB1消息来确认是否存在***消息更新，从而节省了UE的电池消耗。而通过本发明的方法，网络侧只需要在部分T-SI-Paging中发送***消息更新指示，从而降低了在没有***消息更新时发送所述的***消息更新指示而带来的信令开销。
可选的，本实施例的上述***消息更新指示用于指示接收方(如用户设备)没有***消息需要更新，当然，也可以指示有***消息需要更新，或者其他消息的更新情况。

可选的，终端所驻留小区内的一个或多个终端配置相同的短寻呼周期长度，其中，短寻呼周期长度是通过小区配置或根据预定协议约定的缺省短寻呼周期，例如，类似现有LTE***中UE的缺省寻呼周期default paging cycle。
可选的，PTW的长度为T-SI-paging时间间隔长度的整数倍。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机， 服务器，或者网络设备等)执行本发明各个实施例的方法。

终端72，设置为在寻呼传输窗中检测T-SI-paging时间间隔中与终端对应的寻呼时机，并在寻呼时机内接收寻呼消息。
下面结合根据本发明的可选实施例进行详细说明，可以作为本实施例的补充，也可以用于解释本发明：
图8为本发明可选实施例的方法示意图，如图8所示，本可选实施例定义***消息更新之前的一段时间为T-SI-Update，在T-SI-Update中的定义多个时间间隔T-SI-Paging，***在T-SI-Paging中发送携带***消息更新指示的paging消息，UE在其PTW中检测PTW窗内的T-SI-Paging中属于其自身的寻呼时机(PO，paging occasion)，以监听***消息更新指示。
可选的，时间间隔T-SI-Update，其长度为一个小区内最大的eDRX周期长度，或小区通过***消息配置或协议约定的一个周期长度，或BCCH修改周期的长度。
paging消息可以是通过PDCCH信道承载的DCI格式，或者是PDSCH承载的paging message。
可选的，接收方UE都配置相同的short paging cycle(或称为short DRX cycle)，该short paging cycle可以为小区配置或协议约定的缺省的短寻呼周期short paging cycle(缺省寻呼周期：default paging cycle)
特定的T-SI-paging是指在时间间隔T-PTW-Start中的一个或几个paging cycle。T-SI-Paging的长度为小区配置或协议约定的长度，优选的，其长度为小区配置或协议约定的缺省short paging cycle(default paging cycle)。
本实施例的的T-PTW-Start，是指将一个paging H-SFN均匀的划分为若干等份，每一等份的时间间隔。
T-SI-Paging的长度为T-PTW-start长度的N分之一，其中N为正整数。
***通过***消息配置，或协议约定，在一个T-PTW-Start中发送***消息更新指示的T-SI-Paging的位置。其形式包括，一个T-PTW-Start中T-SI-Paging的序号，即第几个T-SI-Paging时间间隔为所谓发送***消息更新指示的T-SI-Paging。或，一个Paging H-SFN中T-SI-Paging的序号，即在Paging H-SFN中第几个T-SI-Paging时间间隔为所谓发送***消息更新指示的T-S-Paging，或所述发送***消息更新指示的T-SI-Paging的起始SFN号。
***在T-SI-Update时间间隔中的每一个T-SI-Paging中的每个PO发送***消息更新指示。
UE在其PTW中的T-SI-Update中监听检测***消息更新指示。
UE的PTW长度大于等于至少一个T-SI-paging的长度。优选的，PTW长度为T-SI-paging长度的整数倍。
在此结合本发明的优选实施例进行进一步说明，图9为本优选实施例的示意图，如图9所示：
定义T-SI-Update为***定义的最大eDRX周期，即m_eDRX，或一个指定的值。其长度为整数个H-SFN或paging H-SFN。每一个H-SFN为***SFN的一个周期长度，一个paging H-SFN为H-SFN长度的整数倍，即一个T-SI-Update包含整数个完整连续的SFN周期或H-SFN。
定义T-PTW-Start为，将一个Paging H-SFN均匀的划分为连续的整数个等份，每一个等份的时间间隔为一个T-PTW-start长度。即一个Paging H-SFN包含整数个完整连续的P-PTW-Start。在本例中，将paging H-SFN配置为一个H-SFN的长度。一个paging H-SFN包含4个T-PTW-Start，即每个T-PTW-Start的长度为256个SFN。
每一个T-PTW-Start的长度为T-SI-Paging长度的整数倍。定义T-SI-Paging的长度为小区缺省paging cycle的长度。本例中将T-SI-Paging的长度，或default paging cycle的长度配置为128个SFN。即每T-PTW-Start中包含2个default paging cycle的长度。
将UE的short paging cycle长度配置等于小区缺省paging cycle长度。
***通过***消息配置，或协议约定，在一个T-PTW-Start中发送***消息更新指示的T-SI-Paging的位置。其形式包括，一个T-PTW-Start中T-SI-Paging的序号，即第几个T-SI-Paging长度的时间间隔为所谓的T-SI-Paging。或，一个Paging H-SFN中T-SI-Paging的序号，即在Paging H-SFN中第几个T-SI-Paging长度的时间间隔为所谓的T-S-Paging，或T-SI-Paging的起始SFN号。
优选的，在本例中，***配置或约定在每个T-PTW-Start中的第一个T-SI-Paging长度的时间间隔为所谓的T-SI-Paging。
在本例中，T-SI-Paging的长度为小区缺省paging cycle，即128个SFN长度，在本例中，一个Paging H-SFN中T-SI-Paging的位置如图9所示。
网络侧在发送更新的***消息之前的T-SI-Update时间内，在每个Paging H-SFN中的每个T-PTW-Start周期中的每个指定的T-SI-Paging中每一个PO发送***消息更新指示。
UE根据其自己的eDRX周期和标识计算得到其监听寻呼的起始Paging H-SFN，如背景。UE根据其标识计算得到其PTW开始的T-PTW-Start。UE根据其标识和default paging cycle计算得到其在一个paging cycle中的PF/PO的位置。
根据本发明的方法，网络侧只在UE的PTW窗中的特定paging cycle中发送***消息更新指示。因为所有的UE的PTW窗都将从某一个T-PTW-Start时间间隔的起始位置开始，所以，***在一个T-PTW-Start时间间隔内，只指定部分(可以是一个或多个)，而不是全部的paging cycle发送***消息更新指示，每个UE的PTW窗都将包含至少一个发送***消息更新指示的paging cycle，即本发明定义的T-SI-paging。
这样，按照本发明的方法，配置T-SI-Paging的长度，也就是paging cycle的长度为T-PTW-Start长度的1/N，则***发送***消息更新指示的开销将为传统方式的1/M，其中M＝N/X，X为一个T-PTW-Start中指定的发送***消息更新指示的T-SI-Paging的个数。
需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述模块分别位于多个处理器中。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
S1，将***消息的***消息更新时间间隔T-SI-Update划分为多个***消息更新指示寻呼周期T-SI-Paging时间间隔；
S2，在一个或多个T-SI-Paging时间间隔中发送携带***消息更新指示的寻呼消息；
可选地，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或 者光盘等各种可以存储程序代码的介质。
可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行基站将***消息的***消息更新时间间隔T-SI-Update划分为多个***消息更新指示寻呼周期T-SI-Paging时间间隔；
可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行基站在一个或多个T-SI-Paging时间间隔中发送携带***消息更新指示的寻呼消息。
可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
